Subject: [PATCH] ARM: dts: overlays: Create custom clocks in /
|
|
|
|
Change [1] removes the simple-bus compatible string from the "/clocks"
|
|
node, preventing any custom clocks placed there from being initialised.
|
|
Rather than reinstate the compatible string and trigger DT warnings at
|
|
kernel build time, change the overlays to instantiate those clocks under
|
|
the root node ("/").
|
|
|
|
